Hi, I made a changes to this series and push it out to the 'tunnel' branch under the nftables tree. I added IPv6 support to this 1/7 patch. However: [PATCH 6/7] tunnel: add tunnel object and statement json support still needs to be adjusted to also support IPv6. I can see JSON representation uses "src" and "dst" as keys. It is better to have keys that uniquely identify the datatype, I would suggest: "ip saddr" "ip6 saddr" (similar to ct expression) or "src-ipv4" "src-ipv6" else, anything you consider better for this. I think this is the only remaining issue in this series IMO. If you follow up, patch based your work on the two branches that I have pushed out for libnftnl and nftables. Thanks.
